Freeze dried coffee is an instant type of coffee that is made from high-quality coffee beans, such as Excelsa, Robusta, Arabica, and others. Freeze dried coffee is usually placed in hot water and rehydrated before using and then is used like any other type of brewed coffee. In addition, freeze dried coffee is extremely portable. It comes in large containers but also individual packets that can be transported in pockets, purses, or lunch containers.
